6d00c429 - [Clang] Do not skip over `RequiresExprBodyDecl` when creating lambdas (#147764)

[Clang] Do not skip over `RequiresExprBodyDecl` when creating lambdas (#147764) When we create a lambda, we would skip over declaration contexts representing a require expression body, which would lead to wrong lookup. Note that I wasn't able to establish why the code in `Sema::createLambdaClosureType` was there to begin with (it's not exactly recent) The changes to mangling only ensure the status quo is preserved and do not attempt to address the known issues of mangling lambdas in require clauses. In particular the itanium mangling is consistent with Clang before this patch but differs from GCC's. Fixes #147650
